FLEXIBLE PIPE-JOINT.

Specification of Letters Patent.

Patented Jan. 26, 1909.

Application filed July 3, 1908. Serial No. 441,823.

To allwhom it may concern:

Be it known that I, CHARLES H. JENKINS, a citizen of the United States,resident of Louisville, in the county of Jefferson and State ofKentucky, have made a certain new and useful Invention in FlexiblelPipe- Joints; and I declare the following to be a full, clear, andexact description of the same, such as will enable others skilled in theart to which it appertains to make and use the invention, referencebeing had to the accompanying drawings, and to letters or figures ofreference marked thereon, which form a part of this specification.

The invention has relation to flexible ball joints, having for itsobject the provision of simple and efiicient means for keeping the ballin position, or to keep it from moving inward of its socket.

The invention consists in the novel construction and combinations ofparts as hereinafter set forth.

In the accompanying drawings, illustrating the invention, Figure 1 is asection of the double form of ball joint, with the parts boltedtogether, on the line 1-1 Fig. 2; Fig. 2 is an end view of one sectionof the double form of joint taken from the inner end thereof; Fig. 8 isa central longitudinal section of the single form of joint, and Fig. 4is a perspective view of one of the stud pieces.

In these drawings the letter a, designates the ball section of the ointand b, the socket section thereof, said socket section having aplurality of inner radially arranged seats a, c, c, three being shown,in which are secured small stud pieces d, d, d, which project radiallywithin the socket section and have each a concave inner face d, which isarranged to abut against the convex outer face 6, of the inner half ofthe ball section. Each stud piece d, has a reduced lug f, which fitswithin the seat 0, therefor and is secured therein by a pin f, thesquare or straight face (1 of the stud abutting against the similarlyformed shoulders c, c, at each side of the seat 0, whereby the stud isrigidly secured in position by the single pin aforesaid. The three studpieces are arranged at equal distances from each other upon the interiorof the socket section of the joint, and act to securely hold the ballsection against displacement.

The use of my invention cuts cost and weight and does not obstruct theinterior of the joint.

Having described my invention, what I claim and desire to secure byLetters Patent 1s:

1. In a flexible pipe joint, a ball section, a socket section havingequidistant interior seats, and a concave annular wall at its outer endadapted to abut against the ball section to prevent outward movementthereof, and means for preventing inward movement of the ball sectionincluding removable stationary stud pieces fitting in the seats of saidsocket section and having concave inner faces abutting against the innerhalf of the convex wall of the ball section.

2. In a flexible pipe joint, a ball section, a socket section havingequidistant interior seats, and a concave annular wall at its outer endadapted to abut against the ball section to prevent outward movementthereof, and means for preventing inward movement of the ball sectionincluding removable stud pieces having reduced lugs fitting in saidseats, and pins securing the same therein, said stud pieces havingconcave inner faces abutting against the inner half of the convex wallof the ball section.

In testimony whereof I aflix my signature, in presence of two witnesses.

CHARLES H. JENKINS.
